2zz-ge Ecu Tunning

[takumi]

Hi there ...

After much discussion with various tuners here in South Africa the major problem encountered on our 2ZZ-GE's is the fact that fuelling is out considerably !!! They all basically gurantee at 7kW at the wheels increase with some claiming increases of up to 18 % over stock in some instances !!

We basically have three options available other than going stand alone -

1. Dastek Unichip

2. Perfect Power SMT-6

3. RAM Mapping

Each person says that their system is the best and works on the 2ZZ-GE, but when i ask for references and dyno's to back up claims it all goes quiet.

So basically i love my car and don't want to do the wrong thing.

Guys could you please help me with advice - I would appreciate before and after dyno's to. What are the trends in Japan in this regard - From what i have seen they favour the Apexi Power AFC II, TRUST E-Manange, but i can't seem to find any concrete on our cars specific.

Also what octane fuel do you guys use ?

Have any of you tried Octane Boosters ? Do They work ??

You can even e-mail me directly tparker@oldmutual.com

Any help will be greatly appreciated
